The May 2015 general election results have been described as a “debacle”, “terrible”, and a “disaster” for the very sizeable polling industry in the UK. At least ten major companies and one prominent private pollster produced regular polls in the run-up to the election. While not unprecedented (the general election of 1992 produced a similarly unpredicted result), the scale of error between what was estimated and the final result has been a major embarrassment for an industry staffed with highly qualified statisticians and researchers, and which often shaped the narrative and debate in the media during the run up to the election.
